TECH CEO Andy Byron appeared to say “f****** hell, it’s me” after he was filmed cuddling on the jumbotron with HR chief Kristin Cabot.

The pair dived from the camera as they flashed up on a big screen in front of tens of thousands at a Coldplay gig in Boston.

Byron – who is married – dived to hide his face by looking at the floor, while Cabot covered her face with her hands and turned her back to the crowd.

Their reaction appeared to show guilt and has since gone viral online with speculation Cabot is the tech boss’ “mistress”.

As a chorus of laughter echoed around the jam-packed stadium, Martin said: “Oh what… either they’re having an affair or they’re very shy.”

The mortifying footage from Wednesday night’s show has gone viral on social media – having been shared millions of times on X and TikTok.

Hundreds have accused Byron of cheating on his wife, and have shared support for her.

According to Byron’s LinkedIn, he has been CEO of software development company Astronomer – understood to be worth more than $1.3 billion (£1 billion) – since July 2023.

Cabot, meanwhile, has been the firm’s Chief People Officer for nine months.

It emerged last night that the Astronomer CEO had raved about the HR chief in a press release when she was recently hired.

Byron called Cabot a “proven leader” when she joined the company in November last year.

He gushed: “Kristin’s exceptional leadership and deep expertise in talent management, employee engagement, and scaling people strategies will be critical as we continue our rapid trajectory.

Calbot released a similarly enthusiastic comment, saying she thought the “real magic happens when you align the people strategy with the business strategy.”

On her LinkedIn, she boasts: “I lead by example and win trust with employees of all levels, from CEOs to managers to assistants.”

One social media user commented: “Sorry for the wife but glad they’re being exposed and embarrassed.”

Another wrote: “How utterly sad.”

A third said: “They are both incredibly stupid, sorry. Why would you go to a concert of all places if you are having an affair.”

Neither Byron or Cabot appear to have addressed affair allegations yet.

The Sun has approached Astronomer for comment.
